It moves to 19 top of electromagnetic drive group is resetted, corresponding electromagnetic coil 21 is powered, and makes permanent magnet 18 that gravity and 15 elastic force of spring be overcome to make
Push rod housing 17 rises, and push rod housing 17 pushes the rotation of touch unit main body 14 to the retracted position of card slot sleeve 16；When one group
Dot matrix is moved to 20 top of positioning electromagnetic drive group, and corresponding electromagnetic coil 21 is powered, and permanent magnet 18 is made to overcome gravity and spring 15
Elastic force rises push rod housing 17, and push rod housing 17 pushes touch unit main body 14 to rotate to the latched position of card slot sleeve 16,
And so on, complete the reset and locking work of multiple groups dot matrix.Wherein, live wire passes through the notch and electromagnetic coil of side plate 8
21 are connected.
As shown in Figure 2 and Figure 3,16 glue of card slot sleeve is fixed on 1 inner wall corresponding aperture of belt in touch unit 13 for specific implementation
Position, 2 glue of rack gear are fixed on 1 inner wall two sides of belt, and 4 eight pieces of rotor are symmetrically distributed in 1 four jiaos of belt, each autogamy of four roots rotor axis 3
It is solid by screw by screw secure fit, backing plate 6 and support frame 10 to close two rotors 4, two bearings 5, bearing 5 and backing plate 6
It is fixed to cooperate, guarantee that distance ensures that belt 1 is tensioned between long two support frame 10 of end.Side plate 8 is fixedly connected on unilateral side by screw
Between long two support frame 10 of end, electromagnetic drive module 7 is fixed by screws on side plate 8, wherein guarantee with electromagnetic drive group with
The distance of touch unit 13.Gear 11 and 2 mechanical engagement of rack gear, gear 11 and 12 transition fit of gear shaft, gear shaft 12 and electricity
9 transition fit of machine, motor 9 are fixed by screws in 8 outside of side plate.Gear 11, motor 9, electromagnetic drive module 7 are assembled into whole
Below body device, the long end belt in lower section is braille flush zone, and the long end belt in top is braille output area.
The working principle of the utility model is as follows:
As shown in Figure 1, shown in Figure 5, illustrate by taking one group of touch unit as an example, by being powered to motor 9, make its gear shaft 12
It rotates and is rotated with moving gear 11, the rotation band carry-over bar 2 of gear 11 moves, rack gear 2 and 1 secure fit of belt, therefore belt 1 carries
Touch unit 13 make periodic motion.When touch unit 13 moves to the top of electromagnetic drive module 7, it is moved to return electromagnetism first
19 position of driving group, electromagnetic coil 21 is powered in return electromagnetic drive group 19 at this time, executes reset command, makes one group of touch unit
13 are completely in returns state；With belt movement, the touch unit of returns state comes 20 top of positioning electromagnetic drive group, fixed
Electromagnetic coil 21 is powered in position electromagnetic drive group 20, executes positioning command, is in the lock state specific touch unit 13.Back and forth
Same operation is carried out, can realize the refreshable function of content of braille point.
As shown in Fig. 7~Figure 12, illustrate by taking a touch unit as an example, touch unit 13 includes that unit main body is touched in contact
14, card slot sleeve 16, push rod housing 17, spring 15 and permanent magnet 18.Touch unit main body 14, card slot sleeve 16 and push rod housing
17 is concentric, and card slot sleeve 16 is fixed on 1 inside of belt, and push rod housing 17 has the one-movement-freedom-degree of Z-direction, touch unit master
Body 14 has two freedom degrees of movement and rotation of Z-direction.There are two detents for card slot sleeve tool, are locked out detent respectively and retract
Detent, when touch unit main body 14, which enters, retracts detent, touch unit is in returns state, relaxing of spring, braille output face
Show as contraction state.If electromagnetic coil 21 is powered at this time, permanent magnet 18 is affected by magnetic forces, and permanent magnet 18 is made to overcome gravity and bullet
15 elastic force of spring rises push rod housing 17, and push rod housing 17 pushes touch unit main body 14 to go in the reaction force backspin of spring
The locking detent of card slot sleeve, touch unit is in the lock state at this time, spring-compressed, and braille output face shows as ejection shape
State.If being powered again to electromagnetic coil 21, permanent magnet 18 is affected by magnetic forces, and makes permanent magnet 18 that gravity and 15 elastic force of spring be overcome to make
Push rod housing 17 rises, and push rod housing 17 pushes touch unit main body 14 to go to card slot sleeve in the reaction force backspin of spring
Detent is retracted, touch unit then returns to returns state.And so on, then the reset of achievable touch unit and locking work.
The principle of device is simple, and it is convenient to operate, and substantially reduces power consumption, it can be achieved that the function that braille point persistently refreshes, reduces
The cost that blind person reads.The design of rectangle is beautiful and area occupied is small, and structure is simple, and component assembly and disassembly also facilitate
Safety.Using four support frames, eight rotors are as positioning, good fixing effect.
